Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of satellite on-board cable, in particular to a satellite on-board cable network rapid acceptance detection system and method for small satellite batch production. BACKGROUND

[0002] The satellite on-board cable branches in a network, and the number of nodes of the cable exceeds several thousand points. In order to ensure the safe and reliable use of the cable on the satellite, it is necessary to conduct acceptance detection of the continuity and insulation before use, so as to timely find and eliminate unqualified products such as poor contact, poor insulation and assembly errors.

[0003] The previous satellite on-board cable network acceptance detection method is in the form of manual detection, and the main tools used are multimeter, buzzer and the like, and single-point continuity test and insulation test are performed manually. The main disadvantages of this manual test method are: large number of single points, large error, and cannot guarantee the accuracy of the test; the test results cannot be automatically saved and output; using megohmmeter and multimeter, test tools such as adapter tool are needed, and three test personnel are needed for the test of one cable; especially in the cable resistance test of multi-branch, multi-core and different types of electrical connectors, point-by-point detection, low efficiency, high work intensity, and easy to cause missed detection and false detection.

[0004] With the emergence of large-scale satellite production mode, the cable network acceptance detection work of batch satellites also needs to greatly improve the detection efficiency and detection accuracy, and the traditional manual cable detection method cannot meet the use requirements of batch models. Due to some characteristics of small satellite batch cable, the existing automatic cable detection technology cannot be well and conveniently applied. SUMMARY

[0005] The present application provides a satellite on-board cable network rapid acceptance detection system and method for small satellite batch production, which is used for batch satellite on-board low-frequency cable network acceptance and ground cable on-board continuity and insulation performance test before on-board, replaces the low-efficiency method of manual "pin jack" test, and improves the efficiency and correctness of cable continuity and insulation test.

[0006] In a first aspect, a satellite on-board cable network rapid acceptance detection system for small satellite batch production is provided, comprising a node table automatic conversion module, a test ground adapter cable, and a cable tester.

[0007] The automatic node table conversion module is used to automatically import the batch production satellite cable network node table, extract cable code, cable name, electrical connector code, electrical connector type, and point relationship information. Then, based on the existing ground transfer cable and electrical connector situation, it analyzes whether the existing ground transfer cable library meets the testing requirements of the cable under test, selects cables that meet the conditions for testing, and eliminates cables that do not meet the conditions. It also quickly matches the satellite cables that meet the testing requirements to the usage list of ground transfer cables, formulates the ground transfer cable usage plan, automatically arranges the satellite cable test batch sequence and ground transfer cable insertion sequence and insertion position, generates a list of ground transfer cable insertion and removal positions and sequence, and exports the converted program.

[0008] The ground adapter cable includes an adapter cable, an electrical connector plug that connects to the cable tester, and an electrical connector socket that connects to the cable under test.

[0009] The cable tester is equipped with a low-voltage continuity test module and a high-voltage insulation test module; the test channels support two-wire continuity testing and insulation testing, and are used to test "one-to-one" single cables and "one-to-many" and "many-to-many" branch cables. It has fault judgment and fault location functions, and automatically reports errors when the test results do not match the input file; it automatically generates cable continuity and insulation test reports.

[0014] The test program export module supports exporting the entire program or in batches after the node table has been converted.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, the node table data parsing and import module extracts the standard batch satellite cable network node table. After confirming the node table to be tested, the node table data parsing and import module automatically decomposes the node table into individual cables, generates a list, and is used to view the branching relationship of individual cables. For the selected cables, it determines whether they can be tested in parallel, completing the screening function of ground transfer cables. If there are untestable items in a certain cable, a report is generated in the window at the bottom of the main interface, explaining the reason for the untestability. If the electrical connector model and the ground transfer cables in the ground transfer cable library both meet the test requirements during the preparation work, the test program is generated according to the design of the node table.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the principle of using the fewest test steps and the fewest insertion and removal times of ground adapter cables is followed when generating test programs; in the process of matching the electrical connector model of the cable with the number of ground adapter cables, if the ground adapter cable with the connector is not available in the library or the number of ground adapter cables is insufficient, the cable cannot be tested in one go, thus maximizing the automatic testing of the cable.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, for cases where no specific model of ground adapter cable is specified, a test program is first generated to remove the branch containing the specified model of ground adapter cable before conducting a continuity test. After the test is completed, a dialog box pops up asking whether to pause the test and perform a manual test or to directly jump to the next test procedure. If the manual continuity test is selected, the system will automatically pause. After the manual test is completed, click "Complete Manual Supplementary Test" to continue to the next test step.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, when the number of ground adapter cables is insufficient to complete the test in one go, the test program first sequentially completes the testable branches, and then judges the branches that cannot be completed. The branch that cannot be tested in one go is ax. First, select the ground adapter cable b0 with the electrical connector model as the beginning; bx-i is the i part of the electrical connectors contained in the branch ax after removing the beginning; MN-1 is the test of all cables after removing the ground adapter cable at the beginning, and there are MN ground adapter cables; the following steps are executed in a loop: judge the matching of bx-i and MN-1, obtain Mi as the cable in the library that matches bx-i, use Mi to test, until the branch ax is tested completely.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the cable tester has the function of importing the program after receiving the node table conversion; the cable tester is used to set the test voltage, current, and time parameters, and to perform cable continuity and insulation tests in groups and batches; and to set the judgment criteria and threshold limits for cable continuity and insulation tests, the cable tester automatically judges the test pass status and alarms for erroneous results; the cable tester automatically generates cable continuity and insulation test reports and stores the data in a designated location.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the electrical connector socket is selected according to the male and female corresponding sections of the on-board electrical connector, and the electrical connector plug is selected as an ERNI type easy-plug electrical connector; the adapter cable, electrical connector plug, and electrical connector socket are made into a ground adapter cable by welding; according to the list of ground adapter cable insertion and removal positions and sequences generated by the node table automatic conversion module, the cable under test is connected to the cable tester through the ground adapter cable; all ground adapter cables are entered and archived in the ground adapter cable library in the node table automatic conversion module.

[0021] Secondly, a rapid acceptance testing method for onboard cable networks for small satellite mass production is provided. This method is applied to the system described in any of the implementations of the first aspect above, and the method includes:

[0022] The node table information conversion module converts the on-board cable network node table into a test application. According to the test program, the corresponding ground transfer cable is selected, and the connection between the cable tester and the cable under test is established. The cable tester then performs automated tests on the continuity and insulation performance of the cable under test in sequence, automatically generates result reports, and completes the cable continuity and insulation performance test.

[0023] In conjunction with the second aspect, in some implementations of the second aspect, the method includes:

[0024] 1) In accordance with the design documents, check whether the appearance of the satellite cables produced in batches is intact, whether the pinholes of the electrical connectors are intact and free of foreign objects, and check whether the cable length and markings are correct;

[0025] 2) The node table information conversion module imports the node table of the star-mounted cable in the batch production, automatically analyzes and parses whether the cable under test meets the test conditions, whether there is a corresponding ground transfer cable to support the test, and selects the cable code to participate in the test according to the model test requirements; for "one-to-one" single cable, the cable code under test is directly selected; for "one-to-many" and "many-to-many" branch cables, the branch code of the cable under test is selected according to the branch.

[0026] 3) The node table information conversion module provides the quantity and type of ground transfer cables based on the selected test cables, and lists the codes of the transfer cables; it specifies the insertion position of the transfer cables of the tested cable, and specifies the test batch and insertion sequence; the node table information conversion module automatically generates the transfer cable connection relationship table and the test cable test program.

[0027] 4) According to the test batch, connect the satellite cable and the ground transfer cable of the first batch one by one according to the transfer cable connection relationship table, and at the same time connect the ground transfer cable and the cable tester.

[0028] 5) Turn on the cable tester, import the generated cable test program into the cable tester, and set the current and voltage test parameters, as well as the interpretation criteria for continuity and insulation tests;

[0029] 6) Follow the test procedure to start the continuity and insulation test of the first batch of test cables. If the test fails, an alarm will be triggered. You can choose to stop the test or restart the test. After the test is passed, a complete test report will be generated.

[0030] 7) After the first batch of satellite cable tests are completed, disconnect the satellite cable from the ground transfer cable.

[0031] 8) Following steps 4)-7) above, conduct tests on subsequent batches of test cables one by one until all test cables have been tested;

[0032] 9) Disconnect the satellite cables and ground transfer cables used in the last batch of tests, and organize and store the ground transfer cables and satellite cables properly.

[0034] Compared with the prior art, the solution provided by the present invention has at least the following beneficial technical effects:

[0036] (2) The node table automatic conversion module used in this invention can analyze whether the existing ground adapter cable library meets the testing requirements of the cable under test based on the existing ground adapter cable and electrical connector situation, and match the ground adapter cable usage list with the satellite cables that meet the requirements. At the same time, according to the principle of minimizing the total number of insertions and removals and maximizing the testing of a batch, it automatically arranges the satellite electrical test sequence and the ground adapter cable insertion sequence and insertion position. Then, it generates a list of ground adapter cable insertion and removal positions and sequence and exports the converted program. This realizes automated scheduling and optimization of test schemes.

[0041] Figure 2 This is a schematic diagram illustrating the principle of the automatic node table conversion module.

[0042] Figure 3 This is a schematic diagram illustrating the composition and working principle of a cable tester. Detailed Implementation

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] This invention provides a rapid acceptance testing system for onboard cable networks in small satellite mass production. The system includes an automatic node table conversion module, a ground-based transfer cable for testing, and a cable tester. It completes the acceptance testing of the onboard cable network and the continuity and insulation performance testing of ground cables before they are connected to the satellite. The testing process of the rapid acceptance testing system for onboard cable networks is as follows: Figure 1 As shown.

[0045] A schematic diagram of the automatic node table conversion module is shown below. Figure 2As shown, the automatic node table conversion module can automatically import the batch-produced satellite cable network node table, extract information such as cable code, cable name, electrical connector code, electrical connector type, and point relationship. Then, based on the existing ground transfer cables and electrical connectors, it analyzes whether the existing ground transfer cable library meets the testing requirements of the cable under test. Cables that meet the conditions can be selected for testing, while cables that do not meet the conditions are eliminated. For satellite cables that meet the testing requirements, a usage list of ground transfer cables is quickly matched, and a usage plan for the ground transfer cables is formulated. Simultaneously, following the principle of minimizing the total number of insertions and removals and maximizing the testing of a single batch, the module automatically arranges the satellite cable testing batch sequence and the ground transfer cable insertion sequence and position. Then, it generates a list of ground transfer cable insertion and removal positions and sequences and exports the converted program.

[0046] The automatic node table conversion module can include an electrical connector information database management module, a ground adapter cable database management module, a node table data parsing and import module, and a test program export module. The electrical connector information database management module can define and manage information such as the connector code, quantity, type, and pinhole location of ground adapter cables. The ground adapter cable database management module can define and manage information such as the code, name, quantity, type, and end connector of ground adapter cables. The node table data parsing and import module supports importing nodes from the satellite cable network and performs matching degree analysis and interpretation on the ground adapter cables required for satellite cable testing, determining whether they meet the testing requirements of the cable under test. It automatically arranges the satellite electrical test sequence and the ground adapter cable insertion sequence and position, generating a list of ground adapter cable insertion and removal positions and sequences. The test program export module supports exporting the converted program as a whole or in batches.

[0047] The specific working process and principle of the node table data parsing and import module are explained below. The module extracts the standard batch-produced satellite cable network node table. After confirming the node table to be tested, the module automatically decomposes the node table into individual cables, generating a list and allowing users to view the branch relationships of individual cables. Users can select single or multiple cables or certain branches of a single cable from the list according to their needs, generating and saving the corresponding test programs.

[0048] The system determines whether the selected cables can be tested in parallel, thus completing the screening function for ground adapter cables. If any cable contains untestable items, a report should be generated in the window at the bottom of the main interface, explaining the reason for the untestability. If the electrical connector models and ground adapter cables in the library can meet the testing requirements of the selected set of cables, a test program should be generated according to the design of the node table.

[0049] When generating test programs, the principle of using the fewest test steps and the fewest insertions and removals of ground adapter cables should be followed. If, during the matching process of cable connector type and number of ground adapter cables, it is found that the ground adapter cable of that type is not available in the library or the number of ground adapter cables of that type is insufficient to meet the one-time test of the cable, efforts should be made to maximize the automatic testing of the cable.

[0050] There are two reasons why a complete test cannot be completed in one go: one is the lack of a ground adapter cable for a certain type of electrical connector, and the other is an insufficient number of ground adapter cables. To maximize automated testing, the following measures should be taken for each of these situations.

[0051] The first scenario involves situations where a specific type of ground adapter cable is unavailable. First, a test program is generated excluding the branch containing that adapter. For example, if there is a cable WX with a Y4-7TK connector, and a Y4-7TK ground adapter cable is not available in the cable library, all connection points to that adapter are removed when generating the test program. That is, only test programs for other adapter relationships are generated before performing continuity tests. After completing continuity tests for all connections except for that adapter, a dialog box appears asking whether to pause the test and perform manual testing or proceed directly to the next test step. If manual continuity testing is selected, the system automatically pauses. After the manual test is completed, clicking "Complete Manual Supplementary Test" continues to the next test step.

[0052] The second scenario involves situations where the number of ground adapter cables is insufficient to complete the test in one go. Assume a cable W01 with AN branches, containing BN electrical connectors, and requiring MN ground adapter cables. First, determine if each branch can be tested completely in one go. Assuming CN branches can be tested completely, the test program first sequentially completes the testable branches, then identifies the branches that cannot be tested in one go. Assuming a branch that cannot be tested in one go is ax, and the number of connectors in this branch is bX, first select ground adapter cable b0 with connector type at the beginning of MN. bx-1 represents the electrical connectors contained in this branch after removing the beginning branch. MN-1 represents all cables tested after removing the ground adapter cable at the beginning. First, determine the compatibility between bx-1 and MN-1. This indicates that M1 is the cable in the library that matches bx-1. Since bx-1 > M1, the untestable connector for this branch is bx-2. Use M1 to test the testable items. Continue determining the compatibility between bx-2 and MN-1 to find the ground adapter cable M2. The untestable connector for this branch is then bx-3. Continue determining the compatibility between bx-3 and MN-1 to find the ground adapter cable M3, and so on until a branch is fully tested. This process can help determine and guide testers in performing step-by-step testing, indicating the steps for extracting and testing ground adapter cables.

[0053] The ground adapter cable includes an adapter cable, an electrical connector plug (connecting to the cable tester), and an electrical connector socket (connecting to the cable under test). The electrical connector socket (connecting to the cable under test) is selected according to the male-female matching section of the satellite electrical connector, and the electrical connector plug (connecting to the cable tester) uses an ERNI type easy-plug electrical connector. The adapter cable, electrical connector plug, and electrical connector socket are soldered together to form the ground adapter cable. A list of ground adapter cable insertion / removal positions and sequences is generated according to the node table automatic conversion module. The cables under test are grouped and connected to the cable tester host in batches via the ground adapter cable for testing. All ground adapter cables are entered and archived in the ground adapter cable library in the node table automatic conversion module. Based on the characteristics of the mass-produced satellite cable network, the most commonly used ground electrical connectors are identified as J14A, J36A, J6W, MM, J30J, CX2, Y27, J599, and over 80 other types. More than 500 cables including these connector types are configured to support the mass-produced satellite cable testing.

[0054] The cable tester includes a control computer and accessories, the main unit of the cable tester and accessories, and cable testing software. For system composition principles, please refer to [link / reference needed]. Figure 3 The cable tester main unit is equipped with a low-voltage continuity testing module and a high-voltage insulation testing module. It has at least 4096 test channels, expandable according to testing tasks, and supports two-wire continuity and insulation testing. It can test single cables ("one-to-one") and branch cables ("one-to-many" and "many-to-many"). It features fault diagnosis and location functions, and automatically reports errors when test results do not match the input file. It can automatically generate cable continuity and insulation test reports. During testing, the cable tester can import programs after receiving node table conversions. Operators set parameters such as test voltage, current, and time according to the test program and requirements, and perform cable continuity and insulation tests in groups and batches. They also set interpretation criteria and thresholds for cable continuity and insulation tests. The cable tester can automatically interpret test pass / fail status and alarm for incorrect results. Finally, it automatically generates cable continuity and insulation test reports and stores the data in a designated location. A control computer is connected to the cable tester main unit to drive the cable testing program and store the test result report after testing. The cable tester main unit is used for low-voltage continuity testing and high-voltage insulation testing of cables. The cable testing software is used during the cable testing process, allowing users to set parameters such as test voltage and current, set interpretation criteria for cable continuity and insulation tests, issue alarms for incorrect results, and automatically generate cable continuity and insulation test reports.

[0055] This invention, based on the aforementioned rapid acceptance testing system for on-board cable networks in small satellite mass production, provides a rapid acceptance testing method for on-board cable networks in small satellite mass production. The method involves converting the on-board cable network node table into a test application program using a node table information conversion module. Following the test program, the required ground-based transfer cables are selected, and a connection is established between the cable tester and the cable under test. Specifically, the test channels on the cable tester are connected to one end of the ground-based transfer cable according to the corresponding points, and the other end of the ground-based transfer cable is then connected to the on-board cable under test. The cable tester then performs automated continuity and insulation performance tests on the cable under test sequentially. Test personnel interpret the cable continuity and insulation compliance based on the test results, and the test software automatically generates a result report, completing the cable continuity and insulation performance test. The specific steps are as follows.

[0056] 1) In accordance with the design documents, check whether the appearance of the satellite cables produced in batches is intact, whether the pinholes of the electrical connectors are intact and free of foreign objects, and check whether the cable length and markings are correct.

[0057] 2) The node table information conversion module imports the node table of the star-mounted cables in the batch production, automatically analyzes and parses whether the cable under test meets the test conditions, whether there is a corresponding ground adapter cable to support the test, and selects the final cable code to participate in the test according to the model test requirements. For "one-to-one" single cables, the cable code to be tested can be selected directly. For "one-to-many" and "many-to-many" branch cables, the branch code of the cable under test can be selected according to the branch.

[0058] First, the onboard cable network node table of the mass-produced satellites is imported into the node table information conversion module. The program has a library of ground transfer cables and electrical connector types. The node table information conversion module can automatically analyze the quantity, specifications, quantity, and specifications of ground transfer cables that match the onboard cable connections, according to the onboard cable testing requirements. It analyzes whether the ground transfer cables in the library meet the requirements to support testing and generates a usage list of ground transfer cables.

[0059] 3) The node table information conversion module, based on the selected test cables, provides the quantity and type of the required ground adapter cables and lists their codes. It also specifies the insertion positions of the adapter cables for the tested cables, and defines the test batches and insertion sequences. The node table information conversion module automatically generates an adapter cable connection relationship table and the test procedure for the test cables.

[0060] 4) According to the test batch, connect the satellite cable and the ground transfer cable of the first batch one by one according to the transfer cable connection relationship table, and connect the ground transfer cable and the cable tester at the same time.

[0061] 5) Turn on the cable tester, import the generated cable test program into the cable tester, and set the test parameters such as current and voltage. At the same time, set the interpretation criteria for continuity and insulation tests.

[0062] The test program for the cable under test is imported into the cable tester to generate a batch test program. After setting the test parameters and interpretation criteria, the cable continuity and insulation tests are performed in batches according to the test program. The system can automatically interpret the pass / fail status and issue alarms for erroneous results. Finally, the system automatically generates cable continuity and insulation test reports and stores the data in a designated location.

[0063] 6) Follow the test procedure to begin the continuity and insulation tests of the first batch of cables. If the test fails, an alarm will be triggered. You can choose to stop the test or restart it. After the test is passed, a complete test report will be generated. The report can be output in suitable formats such as Excel, TXT, and PDF.

[0064] 7) After the first batch of satellite cable tests are completed, disconnect the satellite cable from the ground transfer cable.

[0065] 8) Following steps 4)-7) above, conduct tests on subsequent batches of test cables one by one until all test cables have been tested.

[0066] 9) Disconnect the satellite cable and ground transfer cable that participated in the last batch of tests, and organize and store the ground transfer cable and satellite cable properly.

[0067] 10) Check the test report results. After confirming that there are no problems with the data, turn off the cable tester.

[0068] In summary, this invention proposes a rapid acceptance testing system and method for onboard cable networks in small satellite mass production. By automatically interpreting and converting the node table of the onboard cable network for mass production satellites, it quickly generates cable testing procedures that minimize plugging and unplugging operations during testing. Simultaneously, it establishes a ground-based transfer cable library adapted to mass production satellites, connecting the onboard cables under test to the cable tester via ground transfer cables. Using the automated cable tester, it quickly and automatically completes batch continuity and insulation tests on single cables and multi-branch cables on the satellite. It can also automatically identify various types of errors and issue alarms based on set reference standards. After testing, it can automatically generate cable inspection reports for subsequent analysis, management, and storage of onboard cable data from mass production satellites. This solves the problems of low efficiency, high workload, and susceptibility to missed and incorrect detections in the acceptance testing of onboard cable networks for mass production satellites.

[0069] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims of the present invention.
